Keeping you updated with the latest changes about API of the spam_check method.
The 3 following parameters were removed from the API of the spam_check() method due to lack of demand:
frequency_time_10m - 10 minutes activity
frequency_time_1h - 1 hour activity
frequency_time_24h - 24 hours activity
Instead of these 3 parameters, we added the “spam_frequency_24h” parameter, which shows the number of spam requests from the address over the past 24 hours.
You can always find the API method description here: https://cleantalk.org/help/api-spam-check.
